WIRE-CRIMPING MACHINE.

SPECIFICATION forming part of Letters Patent No. 651,200, dated June 5, 1900.

Application filed November 6,1899. Serial No. 735,990. (No model.)

To crZZ whom it may concern:

Be it known that WQCHARLESMAGEE Mo- BRIDE and FREDRICK JOHN HEYBAOH, citizens of the United States, and residents of 5 Savannah, in the county of Ohatham and State of Georgia, haveinvented a new and Improved Wire-Crimping Machine, of which the following is a full, clear, and exact de scription.

IO This invention relates to improvements in v machines for crimping or forming bends in Wires used particularly for fastening and supporting coiled springs in mattresses. These wires are usually formedbyhandwork, which [5 requires considerable time,'and consequently an increased expense.

The object of our invention, therefore, is to provide a machine by means of which the wires may be rapidly and accurately formed 20 and cut off in proper lengths ready to be attached to the springs and frame, thus reducing the amount of labor and reducing the expense of production.

Vt e will describe a wire-crimping machine 25 embodying our invention, and then point out the novel features in the appended claims.

Reference is to be had to the accompanying drawings, forming a part of this specification, in which similar characters of reference indicate corresponding parts in all the figures.

Figure 1 is aside elevation of a wirecrimpj wheel 13 and equally spaced is a series of ing machine embodying ourinvention. Fig.

2 is a side elevation opposite to that of Fig.

1. Figs. 3, 4, 5, and 6 are fragmentary views 5 showing different positions of the crimpingdie. Figs. 7 and 8 are fragmentary views showing different positions of the cutting and end-turning devices. Fig. 9 is a plan view thereof. Fig. 10 is a section on the line 0 1O 10 of Fig. 8. Fig. 11 is a section on the line 11 11 of Fig. 7. Fig. 12 is an end view showing the driving mechanism. Fig. 13 is a section on the line 13 13 of Fig. 1. Fig. 14

is a fragmentary view showing a dog for im- 5 parting an intermittent motion to the machine. Fig. 15 is a section on the line 15 15 of Fig. 1, and Fig. 16 illustrates one of the wires as formed;

The frame of the machine comprises uprights 1 2, extendedfrom a base 3, from which the frame.

. cured to one of the uprights 2, is a die carrier or plunger 7, to the lower end of which a die 8 is attached, which, coacting with the lower die 9, attached to the upright 2, forms the crimps or depressions 10 in the wire, as will be hereinafter described. Mounted to swing on the upright 2, at opposite sides of the die 9, are guides 11 12 for the wire as it is received from the reel, said wire being fed by means of a wheel 13, which may have a groove in its periphery to receive the wire, and a bearing-wheel 14. This bearing-wheel 14 has its shaft-bearings in arms 15, pivotally connected to the opposite uprights 1, and from the outer ends of these arms a spring yielding connection is made with the frame of the machine. As here shown, this spring yielding connection consists of a spring 16, attached at its ends to rods 17 and 18, connected, respectively, to the arms 15 and to the frame of the machine. This causes the wheel 14 to be held yieldingly against the wire fed by the wheel 13.

We will now describe a means for imparting a step-by-step motion to the wheel 13, whereby the wire is fed at proper distances to properly space the crimps.

Extended outward from one side of the pins 19, adapted to be engaged successively by a lug 20, arranged on a lever 21, mounted to swing on a shaft or rod 22, supported in A spring 23, surrounding the shaft or rod, holds the lever 21 yieldingly toward the wheel 13, so that when the lever 21 is moved in one direction the lug 20 by engaging with a pin 19 will impart a rotary motion to said wheel. When the lever moves in the opposite direction to engage with a new pin 19, its inclined side will come in con-. tact with the end of the pin first engaged, causing the lever 21 to move outward to per- 5 mit it to pass. This lever at its lower end is connected by means of a' link 24 witha crank 25, having its shaft-bearings in one of the uprights 2. On the outer end of the crankshaft is a pinion 26, which engages with a I00 pinion 27, attached to a shaft 28, and also on this shaft 28 is agear-wheel 29, which meshes with a pinion 30 on the shaft of a band-wheel 31, which is driven by any suitable motor. From a crank-pin on the pinion 27 a drawbar 32 extends to a pivotal connection with the carrier or plunger 7.

A frame 33 is adjustably connected to a projection 34, extended'from one of the up rights 2, and mounted to move Vertically in the out-er portion of this frame 33 is a cutterplate 35, having at its upper end a cutterpoint 36. An upward motion is imparted to the plate 35 by means of a cam 37 on a camshaft 38, havingbearin'gs in the frame 33, and on the inner end of this shaft 38 is a crankarm 39, from which a rod 40 extends to aconnection with the outer end of a lever 41, mounted on the upright 2. From the outer end of this lever41 rods 42 43 extend, respectively, to cranks 44 45 on rock-shafts 46 47, mounted in the frame Attached to the outer ends of the rockshafts 46 47 are cutting and bending devices,

here shown as segmental lugs 48 49, to 0perate in conjunction with the cutter-point 36 of the plate 35, and they also operate in conjunction with fingers 5O 51 for bending the ends of the wires, as will be hereinafter described. The finger 50 is rigidly connected to the frame atits upper edge, but the finger 51 is connected to the plate 35, so as to move up and down therewith. The plate 35 by moving down allows any-sized crimp to pass without catching.

livotally connected to the inner end of the lever 41 is a depending arm 52, which is provided with a notch 53 to receive a pin 54,.

pnojected outward from the draw-bar A toggle-link consisting of a section 55 and a section 56 connects the depending arm 52 with the frame of the machine-that is, the upper end of the section 55 is pivotally connected to the frame and the lower end of said section is pivotaliy connected to the outer end of the section 56, while the opposite end of the section 56 is pivotally connected to the depending arm. It will be noted that this section 56 of the toggle-link is longitudinally curved toward the arm 52, so that it may act as a detacher, as will be hereinafter described.

A bar 57 is mounted to slide between rollers 58 59, mounted on the frame of the machine, and attached to this sliding rod is a springfinger 60, which engages with the outer edge of the arm 52. A trip-lever 61, pivoted on the frame of the machine, has its upper end pivotally connected to one end of the slide-bar 57, and the lower end of this lever 61 projects into the line of movement of a pin 62 on the wheel 13 at the side opposite that upon which the pins 19 are placed. It may be here stated that there may be as many pins 19 as desired-th at is, to move the wire any desired distance for the purpose of forming the necessary number of crimps. The pin 62, however, is only to impart motion to the lever 61 to operate the cutting and bending devices at the end of each complete revolution of the wheel 13.

In operation the Wire placed between the wheels 13 and 14 is fed a proper distance by means of the lever 21 engaging its lugs with the pins 19. While the lever 21 is moving in the opposite direction, the plunger 7 will be moved downward, causing the die 8 to force or bend the wire into the lower die 9. Then as the plunger 7 moves upward the lever 21 will be again operated to move the wheels 13 and 14 through another step, after which the dies will again operate. This is continued until the proper length of wire is completed. At this time the pin 62 will come into engagement with the lower end of the lever 61, and by rocking said lever the slide-bar 57 will be drawn inward, causing, through the finger 60,

the arm 52 to be moved to engage the pin 54 in the notch 53, as indicated in Fig. 4. Now jas the plunger 7 moves downward the arm 52 i will of course be drawn downward, which 1 will cause the lever 41 to be rocked, and this,

by means of its connections, will rotate the shaft 38, so that the cam 37 will move the plate 35 upward to its proper position. Then the rock-shafts 46 and 47 will be operated, causing the edges of the lugs 48 and 49, in conjunction with the point 36 of the plate 35, to cut off the finished length of wire from the main length. Then by a continued movement of the shafts 46 and 47 the inner curved edges of the lugs 48 and 49 will bend the ends of the wires around the fingers 50 and 51, as indicated in Fig. 8. During this forward movement of the arm 52 and before the die 8 reaches the wire the curved link-section 56 will engage with the pin 54 and push the arm 52 out of connection with the pin 54. Then a spring 63 will draw the lever 41 to its original position, and consequently move the plate 35 downward and return the cutting-lugs 48 and 49 to their normal position, so that a new length of wire may be crimped throng-h before it is again out off. The position of the machine at this time is indicated in Fig. 6.

To insure a throwing out laterally of a tin" ished length of wire, we employ a discharging-finger 64, which is pivoted to the frame 33 and has its lower end extended downward at the inner side of the wire. On the upper end of the finger 64 is an upwardly-swinging trip-section 65, adapted to be engaged by a,

of the swinging section 65,will swing the same upward without impartingany motion to the finger 64. (See Fig. 8.)

The severed wire is held on the finger 51 during the operation of bending the end by means of a finger 67, extended from one end of the lever 68, and from the other end of this lever (38 a rod 69 extends to a connection with the lever 41. In attaching the wire to a mattress the said wire is engaged with the springs in a line and the hook ends are ongaged around the frame of the mattress.

WVhile we have described the machine as for crimping spring holding-wires, it is to be understood that it may be used for crimping wires used in other connections, and the dies may be of various forms to produce the desired shape of crimp in the wires.
